Senjutsu, also called Sage Jutsu (or Sage Techniques).
It is a gathering of nature energy.
It's all about balancing your physical, mental, and nature energy through mediation. Without balance, you cannot control nature energy.
- Take in too little: You cannot produce sage chakra
- Take in too much: You risk turning into the summoning animal you sign a contract with.
- Those who are overwhelmed with senjutsu chakra turn to stone, becoming nature themselves.
It takes outside energy from the surroundings such as plants, animals, air, etc., and adds to your internal chakra inside your body, resulting in powerful energy that boosts ninjutsu, genjutsu, and taijutsu.
In general, senjutsu can only be used by those who have undergone extensive training, though there are other ways to obtain senjutsu chakra:
- I can be taught in two places: Mount Myboku and Rychi Cave.
- Via genetics such as with members of Juugo's Clan that allows one to absorb through the body and undergo transformation
- Hashirama (unknown)
- Orochimaru via Curse Seal.
Other forms of Sage Mode is called Six Path Sage Mode which is special form of Sage Mode used by the Sage of Six Path, gifted by the Sage Of Six Paths such as with Naruto and Sasuke, or TenTails Jinchuuriki such as with Madara or Obito.
